Squire LN4 Squire Padlock

The Squire LN4 Padlock is part of Squire's 'Lion' range. The padlock lock body is made from solid brass and has a hardened steel shackle, perfect for securing tool boxes, luggage and lockers. It can be used both indoors and outdoors. We recommend this 40mm padlock to anyone looking for an affordable security solution.  All Squire padlocks come with a 10-year guarantee.

At the core of the Squire LN4 is its solid brass body, manufactured to exacting standards that surpass typical commercial padlocks. The 40mm width provides substantial material mass that resists attack attempts, while the precision-machined components ensure smooth operation throughout decades of service.

Featuring a sophisticated 4-pin tumbler mechanism that strikes an ideal balance between security and practicality. The precision-ground pins interface with the paracentric keyway to create effective pick resistance without making legitimate key operations cumbersome. Each lock is supplied with two keys as standard, with the option for additional keys to be cut to code—essential for complex security infrastructures requiring controlled key distribution.

Security practitioners understand that environmental resilience is as crucial as mechanical strength. The Squire LN4's solid brass construction provides inherent corrosion resistance that significantly outperforms plated alternatives in challenging environments. The internal components are manufactured from materials selected specifically for their resistance to oxidation, ensuring consistent operation.

The 22mm shackle clearance accommodates most standard hasps and fittings, while the 6mm shackle diameter provides excellent resistance to cutting attempts. The locks can be keyed alike to reduce key proliferation in multi-padlock installations or incorporated into master key systems for hierarchical access control. This flexibility makes the LN4 particularly valuable for facilities requiring both distributed physical security and centralised management.
